Where to Find the Cartridge Number on Your Printer

The quickest reliable method is to identify your printer’s exact model number, then confirm the cartridge family listed for that model. Do not choose a cartridge based only on appearance: physical fit, electronic recognition, regional versions, and yield can all affect compatibility.

Once you have the confirmed cartridge number, you can Browse cartridges or narrow the search to ink cartridges or toner cartridges.

Start with the exact printer model

Look for the printer model on the following locations:

• The front, top, or control-panel area
• A label on the back, side, or underside
• The printer’s display or settings menu
• Your computer’s printer settings
• The original printer box or purchase record
• The manufacturer’s setup app or support page

Record the complete model name, including letters, numbers, suffixes, and regional designations. A similar-looking model in the same product series may use a different cartridge family.

Printer model versus cartridge number

These are different identifiers:

Identifier	What it tells you	Where to find it
Printer model	The device you own	Printer body, settings, box, or support software
Cartridge number	The consumable family designed for a printer or printer group	Cartridge label, packaging, manual, or manufacturer support page
Product or SKU number	The seller’s listing identifier	Retailer listing or product packaging
Serial number	Identifies an individual device	Printer label or settings page

The printer model is the best starting point when you do not know which consumable family you need. The cartridge number is the confirmation you should use when shopping.

Where to find the cartridge number

Check the installed cartridge

Turn off or open the printer according to its instructions and remove the cartridge only if the manufacturer’s procedure allows it. Look for a printed or molded identifier on:

• The front or top label
• A side label
• The cartridge handle or frame
• A small sticker near the electrical contacts
• The original cartridge box, if you kept it

Write down every visible code. Some cartridges display a prominent family number while also showing manufacturing, regional, or production codes. The most useful shopping identifier is usually the cartridge or series designation, not a serial number.

Do not rely on color alone. A black cartridge and a color cartridge may belong to the same family, but their numbers can differ.

Check the printer’s software or display

Some printers show supply information in:

• An ink or toner status screen
• A maintenance menu
• A printer information report
• The manufacturer’s desktop or mobile app
• A web-based printer management page

The display may show a cartridge family, an abbreviated code, or only an ink or toner level. Treat this as a useful clue, then verify the result against the printer model and an official compatibility source.

Check the manual and official support page

Search the manufacturer’s support documentation using the complete printer model. Look for headings such as:

• Compatible supplies
• Consumables
• Replacement ink or toner
• Supplies and accessories
• Cartridge specifications
• Supported cartridges

This is generally safer than searching by a partial model name. If an official page lists multiple cartridge families, check the exact model, country or region, and printer configuration before ordering.

Check previous packaging or order history

An earlier cartridge box, invoice, or online order can reveal the correct family. Confirm that it was actually used in your current printer. A cartridge from another printer in the same household may look similar but belong to a different family.

Confirm whether the printer uses ink or toner

The consumable type is an important first filter.

Ink cartridges

Inkjet printers use liquid ink cartridges. They may use:

• Separate black and color cartridges
• Individual cartridges for each color
• Combined tri-color cartridges
• Cartridges with an integrated printhead
• Ink tanks or refill bottles rather than conventional cartridges

If your printer uses refillable tanks or bottles, do not substitute a cartridge merely because it is labeled for inkjet use. The printer’s documented consumable system must match.

Compare ink cartridge options after confirming the cartridge family.

Toner cartridges

Laser and some LED printers use dry toner. They may use:

• A toner cartridge
• A separate drum unit
• A combined toner-and-drum assembly
• Additional waste-toner or maintenance components

A drum unit is not automatically interchangeable with a toner cartridge. Check whether the printer requires one component or both, and verify the exact replacement part before buying.

Browse toner cartridges only after confirming whether you need toner, a drum, or another maintenance supply.

Physical fit is not the same as compatibility

A cartridge can appear to fit and still fail to work correctly. Check these compatibility layers separately:

1. Physical compatibility

The cartridge must match the printer’s shape, guides, locking mechanism, dimensions, and contact positions. A similar shell is not proof of compatibility.

2. Electronic compatibility

Many modern cartridges include a chip or electronic contact system. The printer may use it to identify:

• Cartridge family
• Color
• Estimated remaining supply
• Installation status
• Authentication or error conditions

A cartridge that fits mechanically may not be recognized electronically. A compatible or remanufactured cartridge may also require a correctly programmed replacement chip.

3. Region or market compatibility

Some cartridge families are sold under different identifiers in different regions. Packaging, labeling, warranty terms, or electronic recognition may vary. Match the cartridge information to the printer’s purchase region when the manufacturer or seller specifies a regional restriction.

4. Firmware and update risk

Printer firmware can affect how third-party cartridges are recognized. This does not mean every update will cause a problem, and cartridge behavior varies by printer and supplier. However, check the seller’s current compatibility information and return policy before buying a compatible or remanufactured cartridge.

Avoid treating a general statement such as “fits this printer brand” as sufficient. The listing should identify your exact printer model or the verified cartridge family.

Standard versus XL or high-yield cartridges

Many cartridge families have more than one capacity. Common labels include:

• Standard yield
• High yield
• XL
• Extra high yield
• Extended yield

These labels are not universal guarantees. A high-yield cartridge is compatible only when the printer supports that specific high-yield version.

How to compare yield

Use the manufacturer’s stated page yields when available. Compare like with like:

• Black with black
• Color with color
• Standard with standard
• High yield with high yield
• The same page-yield testing method

A basic cost-per-page calculation is:

Cartridge price / stated page yield = estimated cost per page

For example, if a cartridge costs $30 and its stated yield is 600 pages:

$30 / 600 pages = $0.05 per page

This is an estimate, not a guarantee of your actual cost. Page yield can change with coverage, document type, print quality, cleaning cycles, and other printer behavior. Color cartridges also require careful comparison because a listed color yield may not represent equal use of every color.

When high yield may be the better choice

High-yield can make sense when:

• The printer explicitly supports it
• The price premium is reasonable relative to the additional yield
• You print regularly enough to use the cartridge before long-term storage becomes an issue
• You want fewer cartridge changes

Standard yield may be more practical when:

• You print infrequently
• The high-yield version has a much higher upfront cost
• You are unsure whether the printer supports the larger capacity
• You want to reduce the risk of storing an opened cartridge for a long period

Do not assume XL always has the lowest cost per page. Calculate it using verified or clearly labeled yield information.

OEM, compatible, and remanufactured choices

After confirming the cartridge family, you can choose the supply type.

Type	General description	What to verify
OEM	Made or sold by the printer manufacturer	Exact model support, yield, and regional version
Compatible	Newly manufactured by a third party	Cartridge family, chip recognition, stated yield, and return policy
Remanufactured	Previously used cartridge that has been cleaned, refilled, and tested	Reconditioning process, chip replacement or reset, print guarantee, and return terms

An OEM cartridge is not automatically the only workable option, but it is important to understand the trade-offs. Third-party options may cost less, while compatibility can depend on cartridge construction, chip programming, firmware, and the supplier’s quality control.

If you buy a non-OEM cartridge, look for:

• A direct compatibility statement for your exact printer model
• A clear cartridge-family number
• Stated page yield and test basis
• A guarantee against recognition or print defects
• A practical return or replacement policy
• Storage and shelf-life information

Pre-purchase checklist

Before placing an order, confirm each item:

• [ ] Exact printer model, including suffixes and regional details
• [ ] Ink or toner system
• [ ] Correct cartridge family or replacement part number
• [ ] Correct color or black-only version
• [ ] Physical design and installation position
• [ ] Electronic or chip compatibility
• [ ] Regional compatibility, if applicable
• [ ] Standard, XL, or high-yield support
• [ ] Stated page yield
• [ ] Cost per page using comparable yield data
• [ ] OEM, compatible, or remanufactured type
• [ ] Return policy if the printer does not recognize the cartridge
• [ ] Whether you need a drum or other maintenance component instead of, or in addition to, toner

What to do if the cartridge number is unclear

If the label is damaged or unreadable:

1. Record the printer’s complete model number.
2. Check the printer menu or manufacturer’s supply page.
3. Compare the cartridge shape and installation position only as secondary evidence.
4. Search your prior purchase history for a confirmed cartridge.
5. Ask the seller to verify the exact model before ordering.
6. Avoid buying based on a vague description such as “fits most printers.”

If a new cartridge fits but is not recognized, remove and reinstall it according to the printer instructions. Check for protective tape, damaged contacts, or an incorrectly seated cartridge. If the problem persists, confirm the cartridge number, printer region, chip compatibility, and firmware-related information with the seller or manufacturer.

For ink systems, poor output after installation may also result from blocked nozzles, air in the ink path, or a required printhead alignment or cleaning cycle. For toner systems, check whether the printer separately uses a drum unit and whether the cartridge’s protective materials were removed.

Storage and handling basics

Store replacement cartridges:

• In their original sealed packaging until needed
• In a dry location away from excessive heat and direct sunlight
• In the orientation recommended by the manufacturer
• Away from dust, moisture, and physical damage

Do not shake ink cartridges aggressively or touch electrical contacts and printhead surfaces. Handle toner cartridges according to their instructions, and avoid exposing toner to heat or spilling it inside the printer.

Bottom line

Find the exact printer model first, then verify the cartridge family through the installed cartridge, printer software, manual, or official support documentation. Before buying, confirm ink versus toner, standard versus high yield, physical and electronic compatibility, region, yield, and the seller’s return policy. This process is more reliable than matching a cartridge by appearance or brand alone.
